Eli5: square cube law and gaining weight for strength

255 views

I’m trying to build my jump height and have been told repeatedly to stay the same weight and just build strength, even though I could comfortably lose a stone and still be a healthy weight. I recently heard of the square cube law and wondered how this relates to strength training.

Why do people want to gain weight to get stronger when the square cube law seems to indicate being smaller gives you more strength potential pound for pound?

Because youre still stronger in absolute terms.

Also the only way to efficiently add muscle is to gain weight, so even if you want to ultimately weigh less than you do now but have more muscle mass (which would make you stronger both relatively and absolutely) the the best way to achieve that is through a series of bulk/cut cycles where you will at some points be heavier than you were.
